**Polynomial Function Matching**

- Choose a second degree polynomial graph. Match a few graphs. Use the
**Help** feature if needed. Can you explain what effect each value has on the graph?
- Match graphs from all three types. Which values have the same
effect regardless of the degree of the polynomial? What are the effects?

**Periodic Function Matching**

- Choose a sine graph. Match a few graphs. Use the
**Help** feature if needed. Can you explain what effect each value has on the graph? Why do you think this graph is called *periodic*?
- Notice that the function expressions for all the periodic graphs have the same form. Can you explain why?

**Any Function Matching**

- Match at least one function of each function type. Use the
**Help** feature if needed. Name common characteristics of all values in all
function types. Name dissimilar characteristics of all function types.
- Can you explain why the function types are grouped the way they are?
